I am using an EasyVR module with my arduino board ( indian version ) .. The program below is working .. and when i give a voice command it successfully displays the message in the serial monitor .. i want to make an LED on pin 12 glow instead of displaying the message .. i tried replacing the line
if (c == WORDSET_1_ACTION) { Serial << c << " (WORDSET_1_ACTION)" << endl; }
by
if (c == WORDSET_1_ACTION) { Serial << c << " (WORDSET_1_ACTION)" << endl; digitalWrite(12,HIGH) }
it is not working ... pls help me ....

Don't see a "pinMode (12, OUTPUT);" in there...

Please use code tags when posting code.

Before your program gets much bigger, you may want to investigate the use of PROGMEM for all those strings.

Thanks for the reply .... Gave pinMode(12,OUTPUT) in the setup part ... Still Not working ... :frowning:

So, write a little sketch just to test that the LED connected to pin 12 is actually connected and working.
Something like "blink without delay", but use pin 12, not 13 or whichever pin the example uses.

Please go back to your original post, click on "modify", then highlight the code, then click on the # icon on the toolbar, then click on "save".

I tried this code as you mentioned .. and it works ..

void setup()
{
pinMode(12,OUTPUT);
}
void loop()
{
digitalWrite(12,HIGH);
delay(1000);
digitalWrite(12,LOW);
delay(1000);
}

Good, so wiring isn't your problem.

Hey thanks for your replies ... :slight_smile: i have fixed this problem ..

I need to first setup the VR module by connecting it in the pins 2 and 3 while uploading a new program ...

and then to execute the program i need to connect it on pins 0 and 3 ...

Its working fine Now ... XD :stuck_out_tongue: :slight_smile:
